I wanted to thank everyone for the information and the inputs. I've narrowed things down to 40-50 hp range and I'm trying to get turbo for the altitude.
I've visited 4 dealers so far: Kioti (DK50), JD (4120), Kubota (4400 no-turbo), and NH dealer (TC45A, TC55DA).
Next I'm hitting Massey, CAT, and potentially Agco (If I understand things they all sell version of the same tractor made by Agco) they are the 1440/1540, 275B, and ST40 respectively. There are some differences but I haven't gotten it straight in my head yet.
I'm putting a comparison spreadsheet with tractor and FEL specs and price quotes. I'll post it when I have it filled in. Once I understnd the differences a little more I plan to narrow down to 2 or 3 and go from there.
What should I be looking for on the FEL specs besides lift capacity and bucket size?
